Abstract
A blood substitute or blood extender is prepared by chemically coupling hemoglobin with a polysaccharide material selected from dextran and hydroxyethyl starch, and having a molecular weight of from about 5,000 to about 2,000,000, to form a covalently bonded chemical complex. The complex has similar oxygen transporting abilities to hemoglobin, and has a much lower rate of renal excretion.
